Abstract (en)
[origin: WO2016032433A1] A sealing system (20) for an optical sensor of a turbine engine that diverts and exhaust seal leakage away from the seal (22, 24) to prevent ingestion of humid air through the seal (22, 24) is disclosed. The sealing system (20) may include inner and outer optical housings (26, 28) with first and second seals (22, 24) positioned there between separating inner and outer optical housings (26, 28) radially. The sealing system (20) may include one or more leakage manifolds (30) positioned between the first and second seals (22, 24) and containing one or more manifold rings (32). The manifold ring (32) may be positioned between and in contact with the first and second seals (22, 24) enabling the first and second seals (22, 24) to form a double seal. The manifold ring (32) may also be configured to capture leakage air that has seeped past the first seal (22) and exhaust that leakage air through one or more exhaust vents (34) in the outer optical housing (28) before leaking through the sealing system (20).
